Firstly the pros, nicely detailed model, lovely interior for the most part, almost accurate formation (pantograph cars and nameplates on backwards, but can be changed easily), nice inclusion of liveries, especially InterCity. Very well modelled cab, and an especially good inclusion of tilt which can be turned off. Acceleration and deceleration are very good, always fun to start and stop at stations, especially terminus ones for me.
Now the cons, it's sounds are atrocious (compare that to the DTG 321 though :P) and almost nothing like the real thing, especially on the inside. The tilt feels forced and shaky rather than natural, the train is prone to shaking which feels very unnatural for such a structurally sound train, it's not very interactive (I like my start up procedures like the JT Voyager), still some things missing in the cab, though not initially noticeable. It's lack of cab light is also terrible when driving at night, and the career scenarios completely negate the benefit of tilt by removing points for drive quality. Finally, the most obvious con is that of all three liveries, not one of them is Virgin Trains, which is the best one for such a great model.
Overall, I would definitely recommend it, but like everything only get it in the sales. AP needs to do a sound pack, and I wouldn't mind them doing their own one personally. But this is what we have, and it is satisfactory enough for a train that has a special place in my heart and childhood.
